Application filed December This invention relates toresilient disk wheels' and more particularly to wheels ot that general type which are readily assembled or disassembled. i A

Among theobjects of this invention/is to provide a resilient disk wheelvthe paitsfoi which can be locked together with rapidity and with a minimum `amount of labor, said wheel comprising for this purpose amnov'el lockingmeans. l

Another object of this inventionis to pro-- vide a `resilient disk wheel comprising aV plurality oi? parts, and locking nieans'tor securing said parts together positioned along said wheel and acting simultaneously at diij'# 'ferent parts `of the wheelY-whilefsaid parts are heilig engaged to lock the sainel together.

Still another object ofthis invention is to provide a resilient disk `wheelbthe members oit which co-operate inl a unique mannerin vconjunction with al novel `fastening fmeans 4to provide a simple and eiiicient constrnotion..4

l With the foregoing and other objects Ain View the invention consists inthe arrange ment and combinationof parts hereinafter described and claimed, andwhiler the inven tion is not restricted to the exactdetails ot construction disclosed oisuggestyed.he1ein still for the purpose `ofillustrating a practical embodin'ient thereof` reference is had to the accompvanyingy ydrawings in which like reference characters` `designa-te A the same parts in the several views, and in which- Figure 1 is a fragmentary.cross-sectional view o'l'l the wheel assembled in placa Fig. 2 is a side view of a portionof` the wheel looking in the `direction of arrow 2" sectional view on the Fig. 6 is an enlarged sectional view taken on the line 6-6 oi Fig. 2.-

Referring `now 4more Aparticularly to `the drawings, the disk wheel is lshownwin `connection with the usual `pneumatic tire 10` and the ksolid tire 11, the former of which positioned within the resilient wheel so as to support certain parts thereof, while the latter ,is nturn mounted upon an outer circuiti 3,1924. seraiNo. 753,645.: l

terentialportion of lsaid wheel so as to bev resiliently supported thereon., Saidmresilient" Wheel thus comprises two main sections act/- ing individually with said tires, the one acting with `the pneumatictiie being described hereinafter as' the inner section,` while Vthe one actingfwith the outer tire will be desig# a n nated as thel outersection ot the disk wheel.

Y The innerbsection of the resilient disk" 'wheel i'vi'll thus be seen as comprising/supporting means such` as a pluralityfo' supporting Ydisksor plates having `suitable cooperationwwith the axle 12, asby' means of an adapter 13. More specifically, said sup! porting means comprise plates 1liy and 15 spaced from eachother asby means of the N adapter whichhas connection with the plateV 1 4: by" means of a shoulder `.and screw arrangement at 16, while the plate 15 is Vsecured thereto `by means such a'sthiiiiblesl'? l and boltslS passing therethrough, said'plate abutting against adiaiige of the adapter at 19. The plate :14" is', dis'posedgpreferablyr adjacent to a plane perpendicular to the axis ofthe 'wheel and passing `through the center oit' the pneumatic tire, while ,the plate or diskll is preferably at thatside Offhe wheel remote fronithe end of theai'ile. w'llhe plates Alll and 15 `(5o-operate with means for 'supportingthe pneumatic tire through device Comprising M a novel locking means. specifically, said plates support a ycylindrical portioiior member 2Q, said member, having fixed` yengageraentl preferably with the plate y15 and detachable locking engagementwvith the other plate. The lockingdevice aforellli/lore f saidfis madeeiective by a rotarymovementf l or the like of theplatesrelatively to each other, the result ofwhich istogwhollyeflect a strong engagement ot said parts through as large a space orahgle asrmay bedesircd;`

by a. singlewmovement. Thussaid `member has lockingtongues or headed means such `ashooks 20`while the plate 1li `is provided with openings or slots2'1 to receive said hooks to permit of a l rotational .,engagement thereof with theplate as shown iullig.` 5,.. After 'the i disk 15` islastenecb tothe adapter, and the plate lfl` eugagedlwithl the member, 20`as stated.,` saidplate isfsecured to thefada'pter., l

at 16 which then preventsrelative,rotation of the parts of the inner section,` thus insur` -4 ing asure and ,continuous` interlock ofsaid parts. f vThe cylindrical member QOwhich is attached `to a flangey ofthe ,disk-,15, by .Sueblaieteer Sieh as wash-es ai .Henge- 23 for affording lateral support to the pneumatic tire formed along an edge thereof remote from the 'fastening devicewhile plate 1st is provided with n'ieans'loeated in opposite relation to the flange 23 such as a flange 2l for affording lateral support to said tire upon the other side thereof. rl`he plate 14: is provided with means for carrying the member 20, such as a cylindrical portion 25, which is made preferably by forming the plate with an annular convcxity as shown at 26. The cylindrical portion 25 is secured against movement lateral to the member 2O by means of said locking hooks. As thus constructed the inner section of the resilient wheel affords a strong and sure suppoit for the pneumatic tire, and one which will withstand reliably all the rough usage to which it may be subjected.

The outer section of the resilient disk wheel embodies the novel fastening device, whereby it is readily den'iounted as for purposes of repair and inspection7 and also rapidly assembled in place at a minimum expense of time and labor. It has been so arranged and constructed as not only to peiform with the maximum efficiency the usual functions of a. resilient disk wheel, but also to utilize to the best advantage the novel E locking means herein described. The specific arrangement of the wheel construction is an object which is rather subsidiary to the lock-` ing means disclosed, and is intended to be mainly representative of the utility and advantage which said locking means possesses.

Said outer section of the resilient disk wheel comprises a floating member or disk 29, which moves between suitable guide means such as the disk 15 and the brake drum 30. .Said disk is offset adjacent to the pneumatic tiie as at 29a, and then extends into locking engagement with a structuie which is secured to the outer tire 11. Said structure coinprehends a member 31 having means for affording lateral support to said outer tire, and having engagement with the disk Q9 bymeans of the novel locking device.-

Thus said member has a circular flange 3Q extending along an edge thereof. said flange. being slottedas shown at 33. while the disk 2f) is provided with hooks Q0 to enter said slots and engage said member when the same is moved relatively to the other in predetermined nianner as byrotation. Said locking device comprehends .an arrangement to prevent the unlocking thereof. except at.

the will of the operator.` More specifically, it is desirable for this purpose to retain said members against movement and this result is accomplished preferably by using stop,

means such as a bolt 34 engaging the flange 32 with a fiange 35 formed at the edge of said disk. said bolt being spaced preferably between two adjacent hooks. The flange 35. alo serves tocover the slots in the member 3l. The nuts for the bolts 3 have preferably rigid engagen'ient with the outer iiin member as by beingr welded to the flange 32.

Said outer section of the resilient disk wheel is provided with suitable means bearing laterally upon the pneumatic tire, for

,the purpose of securing a relatively rigid wheel structure. Thus the member 31 is provided with an annular inclined flange 3G upon the side of the tire adjacent to the end of the axle. lateral bearing means being provided likewiser at the other side of said tire. The latter mentioned means takes preferalily the form ot an annular member 3T which is secured fixedly to the disk Q9 as at 38. said member having an annular inclined flange at 39 to receive said pneun'iatif.,l tire. The main cylindrical portion of the member 3T lies at the tread of said tire and in direct bearing relation to the member 3l. For the purpose of providing lateral stiffness of the rim portion of said outer section, the two members aforesaid are interlocked. as by means of my novel locking device` at an edge remote from the disk 29. Thus the member 37 is provided with hooks 20 to engage the member 31 at the slots 31 thereof. l'n assembling the outer section as thus far described, said members are interlocked by a rotational movement before the final interlock between the disk 29 and the member 3'] by means of bolts 34 is effected.

A cover 4f) is' provided for the outer ser-- tion of the resilient disk wheel. which has engagement with an axially directed annular wall 4l of the member 3l by means of my improved locking device. To provide la tcral support for the outer tire a flange 42 is provided adjacent to said locking device. and preferably as an extension of the rim 4f. Said annular wall thus comprises a U-shaped portion 43 which is slotted as at44 to receive the hooks 20d for engagement of the vcover with the member 31 as bv a rotational movement or the like. Said locking means comprehends stop means for preventing undesired movement of said cover. such as a bolt L15. thereby controlling the settin'.r of said locking device. 'lhe nut for said bolt is' preferablv rigidly secured or welded in place. The edge portion of said cover at the hooks is arranged to cover said Plots. The outer arm 42 of the U-shaped portion is ofi'- set as shown to receive the edge portion of the cover plate 4f). thus providing for a neat appearance at this joint.

lnv the preferred en'ibodiment of my invention disclosed herein. it will be observed that the wheel is assembled hv movingthe parts thereof into place in a direction parallel to the axis of the wheel. This insures an easy manipulation of the wheel structure. As the most desirable way of accomplishing this end. the hooks have been constructed so that their shanks lie substantially parallel to the axis of the wheel, the slots lying substantially at right angles thereto. lVhile my improved construction has to do primarily with protecting and safety means for the pneumatic tire housed within the protector, it will be noted that the appearance ot the complete i'inished structure is substantially similar' to the noiv largely used disk Wheel construction.
